Totally glassy, right?

as you can see in this aset image the large virtual facets produce large areas of light return and large areas of obstruction and leakage(red, green is light return, blue is obstruction, black leakage) while the small and med virtual facets return smaller chunks.

The lack of smaller chunks is one of the factors that give large tabled ascchers and EC less fire.

Some will get fire from the high crown if they have one. (there is another factor and that is the vertical size of the higher crown facets as the stone is moved creating new virtual facets not seen face up that is a huge factor also)


so in summery a much simplified view of fire and scint in asschers and EC is 3 factors:

1: size of and number of virtual facets face up

2: bending light

3: virtual facets created by the crown facets as it is tilted.

fascinating! Thanks for all the info, storm!! Once again...!

well...I would have to say you should not judge an EC by its numbers alone. By the books, my EC has a large table and low crown (not QUITE as much so as your diamond possibility, but for argument sake, close). Perhaps it could have been cut better, more for sparkle and less for size. But it DOES sparkle, and it throws lots of colors around! And I find it really pretty! Not so much so as a RB, but RB''s are too sparkly for me.


Just my $0.02

you love large scint and fire events and dislike small ones therefore you love your diamond.

Hmmm...I never thought of that (obvious) point before - but you''re totally right....thanks!

I wonder...is there any truth to the opinion that a larger table makes a diamond look larger overall?

maybe but high crowns give a diamond presence.
looking at a 20%+ crown asscher is the definition of presence.

There are people out there that love the classic EC and its kewl that 2 of them posted on this thread :}
You are however in the minority. But thats not a bad thing :}

In the minority of educated PSers, maybe.

Someone I know got one and she didn''t love it but couldn''t figure out why.
One day I was in their office and someone who knew I was into diamonds told her to have me look at it.
I explained the difference and she went back too her jeweler and told him what she wanted and did an exchange and loved the second stone.
Every time I see her she thanks me for helping her get a sparky stone.
The original wasn''t a bad stone the crown height was in the 10% range with a 70% table it just didn''t have the sparkle she wanted and didn''t know how too ask for.

Rubes, you ring is one of my VERY FAVOURITE on PS and what I have seen of the diamond, it is STUNNING!

It does show that sometimes going outside the recommended numbers can result in a fabulous EC!

Thanks Storm for your additions!
